Abstract

Предметом изобретения является способ для изготовления центробежно-литых армированных стекловолокном пластмассовых труб, причем жидкую отверждаемую смолу, которая содержит наполнитель, вместе со стекловолокном, добавками для отверждения, возможно также с песком вводят во вращающуюся матрицу. Последняя при вводе исходных материалов имеет температуру между 40 и 75°C. Для слоев во внешней области трубы используют смолу с временем гелеобразования, которое равно или больше, чем время гелеобразования смолы, использованной для внутренней области трубы, и используют смолу с содержанием наполнителя, по меньшей мере, 40%. Далее после инициирования экзотермической реакции на матрицу можно разбрызгивать горячую воду, чтобы поддерживать температуру матрицы, по меньшей мере, 60°C, пока вытягивают трубу.The subject of the invention is a method for the manufacture of centrifugal-cast glass-fiber-reinforced plastic pipes, and a liquid curable resin that contains a filler, together with glass fiber, additives for curing, may also be introduced into the rotating matrix with sand. Last when entering the source materials has a temperature between 40 and 75 ° C. For layers in the outer region of the pipe, a resin with a gelation time which is equal to or greater than the gelation time of the resin used for the inner region of the pipe is used, and a resin with a filler content of at least 40% is used. Further, after initiating an exothermic reaction, hot water can be sprayed onto the matrix in order to maintain the matrix temperature at least 60 ° C while the pipe is being pulled out.
